Key result
The combination of doxorubicin (2 µM) and high-dose vitamin E (120 µM) significantly increased cytotoxicity against breast cancer cells compared to doxorubicin alone (P=0.000), with minimal side effects on normal cells.
Why the study?
This study aimed to evaluate the in vitro synergistic anticancer effect of doxorubicin combined with vitamin E.
Does the combination of Vitamin E and doxorubicin improve cytotoxicity against human breast cancer cells in vitro compared to doxorubicin alone?

Should not yet change practice; leaves open whether vitamin E augments doxorubicin efficacy in vivo or clinically.
Does the combination of Vitamin E and doxorubicin improve cytotoxicity against human breast cancer cells in vitro compared to doxorubicin alone?
p-value: p=0.000
In vitro, high-dose Vitamin E synergistically enhances the cytotoxicity of doxorubicin against breast cancer cells while minimizing toxicity to normal cells.
A 2022 study studied Breast cancer (in vitro). Vitamin E combined with doxorubicin vs. Doxorubicin alone or untreated control was evaluated on Cytotoxicity (antiproliferative effect) (p=0.000). The combination of doxorubicin (2 µM) and high-dose vitamin E (120 µM) significantly increased cytotoxicity against breast cancer cells compared to doxorubicin alone (P=0.000), with minimal side effects on normal cells.
